Analog Devices Debuts ADP3088/ADP3089 Regulators

March 17, 2002 by Jeff Shepard

Analog Devices Inc. (Wilmington, MA) introduced its new 1A ADP3088 and 1.5A ADP3089 1MHz non-synchronous buck switching regulators. Packaged in a 3mm x 3mm, space-saving, eight-pin, chip-scale package, the ADP3089 works up to a 12V input with a 11.5V maximum output and is suitable for consumer, industrial and computer applications. The ADP3088, housed in a MSOP-8 package, works up to an 11V input with a 10.5V maximum output, and is suitable for battery-powered equipment and a variety of consumer, industrial, portable, computer and instrumentation applications.

The regulators provide accurate, stable, stepped-down, regulated output voltage, and a cost-effective, efficient power solution. Other features include a high pulse-width modulation operating frequency to reduce external component size and ease noise filtering; an integrated power switch to reduce external component count; three-percent output regulation over line, load and temperature to increase system accuracy; power saving and shutdown modes to reduce quiescent current and save battery life; cycle-by-cycle current limiting for circuit protection; and space-saving packages to reduce solution footprint and cost. Both switching regulators operate over the -40 to +85 degrees C temperature range.

The ADP3088 and ADP3089 are priced at $2.02 and $2.49 per unit, respectively, in 1,000-piece quantities, and both are available from stock.
